ADAU1701 AUX controlled "graphic EQ" possible?
Is it possible to design an eq with fix frequency and Q and make the cut/boost variable with an external potentiometer? I want to use the four aux analog inputs to controll some fixed frequencies live

Aux ADC value settling time
Hi, I'm referring to discussion https://ez.analog.com/message/69629 I also try to get 5 input signals with 4 aux ADCs on the ADAU1701 by multiplexing one of them. The question is how long must I wait

First value read by ADC can vary from chip to chip?
I'm reading an Aux ADC and then holding the minimum value with a slow release time. This has only been a problem on 1 out of 7 prototypes, but on that one, the value is held much lower than it should

ADAU1701 AUX_ADC volume control won't zero output
Hi all. I'm having a problem getting the aux audio adcs to turn the level down to zero with the adau 1701. The best I can do is about -36db which equates to about 40mv p/p. Basically what I have is a
